I just read about a new fabric called Power Felt that is able to produce electricity using lost heat. Think of a world where you have something that uses your body heat to power your personal electronic devices. How much money could we save this way? According to the video linked here, it would only cost $1 to have the fabric attached to a device.
What an interesting way to pursue greener technologies. Not to mention there can be a whole new market for making this material fashionable. Instead of wearing tin foil suits like they do in old science fiction movies, we can be bouncing around in brightly colored clothes that can be used to charge your cell phone. Now when you meet someone new, there might really be sparks flying! (Bad joke, I know. I can't help myself.)
